Я пытаюсь распознать вихри Eddystone с помощью форм iphone и xamarin, поэтому я выбираю этот пакет nuget, чтобы добиться цели: https://github.com/andijakl/universal-beacon/
В Android он прекрасно работает и распознает все типы маяков, включая вихревые. С ios маяки распознаются, но я не могу получить их тип и идентификатор. Итак, я увидел, что в библиотеке есть класс CocoaBluetoothCentralDelegate, который не анализирует информацию полностью. Я частично уверен, что есть что-то с этим закомментированным кодом, но я не понимаю, как извлечь информацию, которая мне нужна, из AdvertisingData. Спасибо всем, что ответит мне!
Я тоже нашел этот ответ, но он не полный и он мне не помогает:
